    Background: The extruded debris and irrigant out of the apex during root canal treatment are one of the major causes of untoward events that can happen during root canal therapy. The aim of this in vitro study was to evaluate and compare the extruded debris and irrigant by using three rotary Ni-Ti systems and one hand instrumentation technique. Method: Forty singlerooted freshly extracted teeth were randomly and equally divided into the four groups. The teeth were fitted in the preweighed Eppendorf’s tubes using analytic weight measuring machine. The teeth were instrumented with Protaper universal (Dentsply Maillefer, Ballaigues, Switzerland) in Group I, Protaper next (Dentsply Maillefer, Ballaigues, Switzerland) in Group II, Adaptive file system (TFA; SybronEndo, Orange, CA) in Group III and Step back technique in Group IV. The extruded irrigant was measured fi.. Read More»
